Despite the superior weatherproofing and wider aperture of 12-40, if they are used for similar pictures within normal parameters will there be a noticeable difference in a 9" x 13" print. I ask because I am tempted to get a 12-40 but I wonder if there would be an apparent difference when used in good light for landscape ( my usual genre ) and the cost would be quite sacrificial !
Real life experience rather than quoting MTF figures from magazine tests would be preferred😀
